It has a misfire code and dumping fuel when its idling.

Nothing wrong w/ the O2 sensors, they're brand new but somehow the DS is either lazy or staying btwn 300 mv to 700 mv at idle... the PS is osculating up and down real good though.

Cam is 222/226 EPS cam w/ stock 243 heads, supporting mods of course and typical pulley/full exhaust/LS6 intake/28.8lb inj/lid/ported MAF/FRA and FROST bolt on tune.

I'm not asking for a hand me down tune however I am asking for help to get this misfire fix and get the O2 sensor working good again because it was working well before the heads and cam swap.

I have HPTuners PRO so if you can just point me to a direction to correct my misfire as I think its a false misfire due to the cam change and hopefully it'll fix my O2 sensor problem.

Once I get that done I'll press on and get a real dyno tune once I get a day off or two.

Thanks.

Need to fix the misfire. Did you swap the injector data out for the new injectors? You can get the data from a 01-02 car with those injectors. Check the plugs and wires and make sure they aren't fouled or burnt.

It may help if you posted up a log showing the problem & your tune.

Steve aka FROST took care of the injector data. I'll check the wires and the plugs but all of them are new.

Okay, replaced my ported MAF ends w/ a stock one- with a screen... Checked all the plugs, coils, wires... they are firing. I have temp digital scanner and all banks/exhaust ports are 430ish degrees within range.
